Here are a few more places to look...
How do your isolation & tie down pads look? Is there any debris between the bed plate and machine beam? Are the bolts to the tie downs & isolation pads installed correctly? If you back off spring tension one roller at at time on the rail guides is there any change? Did you change the ropes? Is the vibration different in opposite directions? Are the new compensation chain the same weight as the old chains?
Also, Can you post a picture of the motor mounted to the machine?

A few more idea's. How are the velocity and position encoders mounted. a bad mount , especially on the velocity encoder will transfer vibrations. also I agree with jkh, about Machine vibration. Were you able to tram the new motor to the Brake pulley. Think of it as 2 circles, one inside the other, if they are not perfectly even around the whole circumference, vibration will occur. Lastly we always used a nylon isolation between the Motor pulley and the Brake pulley on a MOD.
